therefore it will only be necessary to point out the characters 

 which will separate them. 



Tinyis pyri. Tinyis pyrioides. 



Disk of the elytra from the apex Disk of the elytra from the apex 



of the rhomboidal cell with rive of the rhomboidal cell with three 

 transverse rows of irregular meshes. transverse rows of irregular meshes. 



Pronotum, lateral margins more 

 upright than in T. pyri. 

 Length 1^ line. 



I have only seen a single example. 



Genus Monanthia, Lep. et Serv. 



Monanthia monstrosa. 



Pale cinnamon-yellow. Pronotum, side margins overlapped 

 and produced posteriorly into a large bladder-like process of- a 

 dark chocolate-brown colour. Elytra with a dark brown or 

 blackish patch in the middle of the anterior margin, and 

 another smaller one of the same colour near the apex ; anterior 

 margin at the base and beyond the central dark patch with 

 two rows of meshes ; on the patch itself the meshes are 

 minute. 



Head black. Crown in front pale brown, and armed with 

 five spines of the same colour placed as follows, viz. a short 

 central one, one on each side in front (approximating and 

 appearing but as one between the antenna?) , and another ap- 

 pressed one along the inner margin of each eye. Antenna} 

 thin, pale clear brown, fourth joint wanting. Eyes black. 



Thorax. — Pronotum pale cinnarnon-yellow, narrow in front ; 

 sides almost straight ; the overlapped side margins produced 

 posteriorly into a large bladder-like process of a dark chocolate- 

 brown colour, and covered with large, for the most part five- 

 sided meshes ; hood small, anterior margin in the middle angu- 

 lated; side keels of the scutellar process in a line with the inner 

 margin of the cysts, the middle one, between the latter, appa- 

 rently clothed with fine brown hairs. Elytra, anterior margin 

 gradually widening to the gently rounded middle, then sinuate 

 to the broadly rounded apex ; marginal field narrow, with two 

 rows of transparent meshes from the base and beyond the 

 dark brown or blackish middle patch, in which last the meshes 

 are minute ; reticulation of the outer row of meshes beyond 

 the patch black and Y -shaped ; disk within the cells flat, 

 brownish ; outer nerve cinnamon-yellow ; meshes finer than 

 those on the cysts, posterior to the cells with a dark brown or 

 blackish cloud, and the meshes gradually becoming larger
